Since the quadrilaterals are similar, then, corresponding sides of them are proportional. Then:


(BC)/(AB)=(RS)/(QR)

Substitute the length of each segment into the equation and solve for x:


\begin{gathered} \Rightarrow(x)/(12)=(4)/(6) \\ \Rightarrow x=(4)/(6)*12 \\ \Rightarrow x=8 \end{gathered}

Therefore:


x=8
